Abstract
Light-induced valence tautomerism (LIVT) of a dinuclear complex, [{Co(dpqa)}2(dhbq)](PF6)3 (1), was investigated by ESR analysis of dhbq3-. LIVT phenomena were observed in the sample diluted in the glass matrix as well as that in powder form. The signal decay and the relaxation were analyzed by double exponential fitting; the results suggest a two-step mechanism. Quantum mechanical tunneling was clearly observed in the glass matrix. Light-induced valence tautomerism (LIVT) of a dinuclear complex, [{Co(dpqa)}2(dhbq)](PF6)3 (1), was investigated by ESR analysis of dhbq3-. LIVT phenomena were observed in the glass matrix as well as in the powder sample. The signal decay and the relaxation, analyzed by double exponential fitting, suggest a two-step mechanism. Quantum tunneling phenomena were clearly observed in the glass matrix.
